Discussions

  • We will go back to labeling specific releases instead of release series to better track work in the next release

Support Update

  • NERSC (Derek, Marian): Continued work to set up non-root XRootD caching for CMS workflow, deploying service certificate to manage data access
  • Syracuse (Edgar): path issue turned out to be a CE configuration issue (SOFTWARE-3035)

OSG Release Team

  • VO Package Release expected this week (VO Package v77)
